BAG' SWIVEL'. l pl Application led December 2, 1922. Serial No. 604,539.

To all whm t may concern.'

lBe it known that I, MYRoN R. SCHALL, a citizen of the United States, residing at Monte Vista, in the county of Rio Grande and State of Colorado, have invented vnew and useful Improvements in Bag Swivels, of which the following is a specification.

This invention relates to supports for punching bags or the like.

It is the purpose of this invention to yprovide absolutely noiseless swivel support for punching bags, and ,one which will work with the desired degree of smoothness and accuracy.

Another object of the invention resides in the provision o'f means, in the nature of a strap for attaching the bag thereto, and permitting proper adjustment of the strap as the occasion requires, and thereby eliminating knotting of the cord within the swivel as is usually done.

The nature and advantages of the invention will be better understood when the following detail description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein: r

Figure 1 is a view partly in section, showing the bag support with the rope of said bag attached thereto.

Figure 2 is a detail view of the socket member.

Figure 3 is a similar view partly in sec tion of the removable cap.

Figure 4 is a sectional view through the ball member showing the strap associated l therewith.

In carrying out the invention, I provide a ball and socket support, which is absolutely noiseless, and one which works very smoothly and accurately. The socket member is indicated generally at A, and includes an attaching plate 10 having an opening 11 to receive suitable fastening elements for securing the plate to the platform 12. Projecting from one side of this plate is a cylindrical portion 13 which is reduced and threaded as at 14, the reduced portion delin-` ing an annular shoulder 15. I`he',reduced`v portion is formed to provide a socket 17 to accommodate the ball 18' as shown. The' ball is retained within its socket by means of a cap 19 which is threaded on the reduced portion 14 and which bears against the shoulder 15 above referred to. The cap is provided with a central opening at one end through which the ball partly projects, and which permits perfect freedom of movement of the ball within the cap and said socket. The construction and arrangement of parts is such, that the ball works very smoothly and accurately within the socket, and thus eliminates that metallic rattling and noise usually present with other devices of somewhat similar character, and which /noise is usually very aggravating to the user of the bag. It is, of course, to be understood that the ball is properlyr lubricated to insure smoothness ofoperation and accuracy.

The ball is provided with large and small communicating bores 20 and 21 respectively and projecting from the small bore is a strap 22, including a buckle, by means of which the strap can be adjusted to properly position the ball with relation to the platform. The strap is looped at one end as at 23, this looped portion of the strap receives a small piece of steel 24 which together with the loop is fitted within the large bore 2O of the ball to hold the strap associated with the latter. This construction allows the strap to be quickly and easily attached to the ball and adjusted to properly position the ball with relation to the platform, eliminating knotting of the rope supporting the ball, within the swivel member which is usually necessary in device of this kind.

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may be resorted Vto when desired as fall within the universally supported bell having e recess therein which' opens upon one side of the lhally and further provided iWith an elongated slot in communication with one end of 5 the recess and open upon the bell at a point diainetrically opposite that end of the opening which opens upon the ball, a pin, extending transversely throufrh the recess and a` looped strap passing through the slot and engaged With the pin, the strap being adapt- 10 ed to be attached to'astriking bag.

In testimony whereof I eix my signature.

MYRON R. SCHALL.
